City council officials have approved a 40 million plan to protect and restore the remains of the wall that used to separate communist East Berlin from West Berlin. Currently 25 of the 34 remaining sections of the Berlin Wall are preserved as national historical monuments. The new project includes improved conservation and protection for all 34 remaining sections, the construction of an information booth at the new Brandenburg Gate underground station and the creation of a clearly marked path tracing the 96-mile perimeter of former West Berlin. Completion is scheduled to coincide with the 50th anniversary of the construction of the wall in 2011. One of the most tangible symbols of the Cold War period, the wall fell on 9 November 1989.
